[Halld-offline] access to jlab-resident data-challenge data

[Mark M. Ito]

First let me stress that these are stop-gap instructions. I am still 
trying to figure out the srm, etc....

There are about 19,000 rest format files at jlab in the directory

   /volatile/halld/home/marki/proj/dc_01/rest

for anyone who wants to take a look. This is about 900 million events 
using 1.7 TB. Each file is about 100 MB. You must be on a farm or ifarm 
node to see the disk.

Any member of the "halld" group should be able to read them. (If not, 
let me know.)

Also note that all of these files have been backed-up to tape. So the 
"volatile" thing is not as scary as it sounds.
